Solution Overview
Problem
Portable suction devices face inefficiencies due to pressure losses from sharp air deflections and baffle plates, leading to reduced runtime, increased size, and complex emptying processes, along with design restrictions and higher production costs for protecting electronic components.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If baffle plates and air deflectors are used to separate suction material from suction flow, then separation effectiveness is improved, but pressure losses increase and device efficiency decreases
Solution Approach 1:
The patent removes traditional baffle plates and air deflectors from the separation process. Instead, it extracts only the essential function of separation by using the natural flow dynamics and the geometry of the suction material guide itself to achieve separation without additional deflecting components, thereby eliminating the associated pressure losses.
Solution Approach 2:
The suction material guide serves as an intermediary element that performs both the guidance of suction material and the separation function. By using the guide's geometry and positioning as the mediating mechanism rather than separate baffle plates, the system achieves separation with minimal interference to the airflow.
2Reliability
If baffle plates and air deflectors are used for separation, then separation effectiveness is improved, but device size increases
Solution Approach 1:
The patent eliminates separate baffle plates and air deflectors, extracting only the essential separation function which is achieved through the integrated design of the suction material guide and housing geometry, thereby reducing the overall device volume.
Solution Approach 2:
The separation function is merged with the suction material guide and housing structure. The guide's geometry and positioning within the housing provide separation without requiring additional space for separate baffle plates or deflectors, achieving compact integration of multiple functions.
3Reliability
If suction material guide has complex geometry to prevent backflow, then backflow prevention is improved, but manufacturing complexity and installation space increase
Solution Approach 1:
The suction material guide is divided into multiple segments or parts that can be manufactured separately and assembled together. This segmentation allows each part to have a simpler geometry that is easier to manufacture, while the combined assembly achieves the complex backflow prevention function through the relative positioning of the segments.
Solution Approach 2:
The suction material guide components are designed to nest within each other or within the housing, with simpler geometric forms that fit together to create the overall complex backflow prevention geometry. This nesting approach reduces manufacturing complexity while maintaining the required functional geometry.
4Reliability
If electronic components are protected by separate watertight unit, then protection reliability is improved, but device complexity and production costs increase
Solution Approach 1:
The protection function for electronic components is merged with the existing housing structure. Instead of using a separate watertight unit, the housing itself is designed with integrated watertight features and sealing elements that protect the electronics, thereby reducing device complexity while maintaining protection reliability.
Solution Approach 2:
The housing structure serves multiple functions: it provides structural support, contains the suction and separation processes, and simultaneously protects electronic components through integrated sealing and watertight design. This multi-functionality eliminates the need for separate protection units and reduces overall device complexity.
